O presente estudo buscou determinar através da técnica FT-IR e Raman, características do solo coletado no sítio arqueológico ‘Templo dos Pilares’ localizado no município de Alcinópolis. Através da análise de FT-IR, pode-se observar que os átomos de compostos orgânicos podem ter sua vibração com amplitude aumentada ao redor das ligações covalentes que os ligam, nesse processo cada mudança de nível de energia vibracional corresponde uma série de mudanças de níveis de energia rotacional e assim originando as bandas com diferentes comprimentos de ondas observadas no espectro.APPLICATION OF FT-IR AND RAMAN SPECTROSCOPY FOR CHARACTERIZATION OF SOIL OBTAINED IN EXCAVATION AT THE PILLARS-MS TEMPLE ARCHAEOLOGICAL SITE, MATO GROSSO DO SUL ABSTRACTThe present study sought to determine, using the FT-IR and Raman technique, characteristics of the soil collected at the archaeological site ‘Temple of the Pillars’ located in the municipality of Alcinópolis. Through the analysis of FT-IR, it can be observed that the atoms of compounds can have their vibration with increased amplitude around the connections of the bonds that connect them, in this process each change of level of vibrational energy corresponding to a series of level changes of rotational energy and thus originating the bands with different wavelengths observed in the spectrum.Keywords: FT-IR; Characterization; Archaeological.

This paper presents an overview of data obtained on the intramolecular vibrational energy distribution in infrared multiphoton excited CF2HCl, CF2Cl2, SF6 and CH3CHF2. All but CF2HCl show collisionless changes in the intensity of the spontaneous Raman signals after excitation, indicating that the excitation alters the population in the Raman active modes. A comparison of the spectrally integrated intensities of the Raman signals yields information on the distribution of vibrational energy over the modes of the molecule. The results for CF2Cl2 show a nonthermal distribution of energy after the excitation.
